"This invention relates to, a time recorder especially designed fortelephone 'users. I I Statistics showthat persons availing theme selvesof the use of longdista'ncef telephone service. almost invariablyconsiderably less time than the eriod allotted by ,the telephone,company. eiusualj minimum chargezlisg for three, minutes',and ofcourse, the customeris entitled to the first three .but' as thereordinarily lino checklon 'time,th'e..user, out of abundantprecaiition,.cuts ofi sooner is required andfrequently 'although.'.a' userf pays'forthree minutes service, he does not use over two minutes.',';,

I have'provided a device which will give a visual record of: the passingof time during the conversation and'which will'actu'ate an 10 audible'gnahjust in advance of the time period soIjthat the "usen can "observethe passing of'tiine during the cbnver'sationand will bereminded thatthe period about to terminate earlyf enough in' advance to complete theconversation before another period m h. b t. I I v.

'I havefalso provided'a chart oi: dial over which a" styluspasses togive. a graphic record of the-time of conversation and to indicate thereare anyinterruptions or interferences, such as cut in on the line orother annoyances encountered by users of telephones. i

The novelt of the invention will be clearly understoo by reference tothe following description in connection with the accompanying drawings,in which-- Fig. l is a perspective view of a complete time recorderconstructed in accordance with my invention.

Fig. 2 is a vertical, longitudinal, sectional view through the same.

Fig. 3 is a cross sectional view on the line 3-3 of Fig. 2. p h Fig. 4is a detail view of a g'earin 'for setting back the ratchet mechanism,an Fig. 5 is a perspective view of the stylus lift cam and the fingerfor lifting out the pawl from the ratchet wheel.

The mechanism is placed in a drum 1 which constitutes a case with aglass window or panel 2 at the top. Between the upper and lower ends ofthe case are two partitions 3 and 4 forminga motor compartment 5 inwhich is a SPIIDO' motor 6. The spring motor drives a hofiow shaft 7 inwhich is loosely mounted a. shaft 8 carry mg at itsnpp'er end a stylusarm 9 at right angles to theshafts '7 and 8 and extending across theslots;10and 11 at the end of the shaft ,7. Therefore, when the hollowshaft 7 turns, the arm 9 must turnwith it. lhe

motor 6 can 'be wound by'a stem 12. The Shaft'Tcarries' a ratchet whc'ellii adapted to {be engaged by the toe 14 of .,a spring-pressed-pawl 15,;the toe being.- urged into engagementWithltheteeth ratchet by the spring17;

On the heel of the par l abell l7', adapted to strike agongcr bell,18 atintervals of one minute because the, teeth 16 are spaced apart to ridepast: the toel l H at the rate of one a minute. At one portion oftheratchet is a spacing l9 which will represent a period 'ofthreeminutesforthe 1 minimum period so thatwhen" the operator begins to talk,the gong.- will not ring for three minutes or shortly before threeminutes and-then the teeth" l 6 will cause the gong to ring each minutethereafter. Y

The time of adjustment can be made by loosening the set screw '20passing through the hub 21 of the ratchet 13 so that the ratchet can beadjusted axially with respect to the toe 14: of the pawl 15. 4

As the shaft ,7 rotates in the bearings 22 and 23in partitionplates 3and 4, the arm 9 will be rotated with'it. The speed of the shaft will beabout one-half hour per revolution so that the stylus or pencil 24on'the end of arm 9 will make a complete revolution every thirtyminutes, or it will move at the rate of. one revolution every thirtyminutes. It will move upon the uppermost one of a stack ofcharts ordials- 25 which rest upon the plate 3 and which will be provided withopenings 26 and 27 to receive the pins 28, and 29 on the partition 3 sothat the cards, disks or charts 25 will all properly align to have thestarting point 30 for the stylus always in the same relative position.

The outer edge of the chart is provided with calibrations 31 dividedinto minutes, halves and quarters'of minutes so that as the stylus movesover the calibrated portion it will write upon the face of the disk theactual time that the arm is moved. Therefore, the user can tell from hischart just how long he has talked.

The motor, of course, will be started by a suitable starting lever 32outside the case
